Abstract: A method to monitor an operating characteristic in a combustion engine: creating a monitoring matrix divided into a number of sections for storage of information, wherein each section is associated with specific intervals of engine speed ? and torque requested from the engine T1. When the engine is used during an operational time window with a pre-determined duration, measuring or estimating an operating characteristic and associating the characteristic with the monitoring matrix's respective section, associated with the current engine speed and the torque requested. For each section in the monitoring matrix, calculating at least one statistical parameter describing the operating characteristic associated with this section during the current operational time window; storing the statistical parameter(s) in the respective section.

Abstract: The invention relates to a wind turbine rotor having one or more wind turbine blades mounted on a rotor hub, the blades having a tip portion and a root portion; a service platform mounted on the wind turbine rotor providing access to the blade root portion of a wind turbine blade, wherein the service platform comprises: a walkway for a wind turbine service engineer.

Abstract: The present invention relates to the control of fuel pressure in a common rail engine in connection with an automatic gearshift procedure. Upon receipt of a primary gearshift command, a fuel pressure in the common rail fuel system is decreased. This decrease is initiated during a time interval prior to reducing engine torque. A gear is released after the engine torque is lowered, thereby enabling a smooth gear release.

Abstract: We present an optical probe arrangement that surrounds blood in a receptacle. It comprises LED's and light detector arranged to overcome the variations when the receptacle is translucent medical tubing and the like. Also, a signal processing algorithm is used to average signals from a plurality of light detectors, to further enhance results when measuring hematocrit. The invention makes it possible to add the feature of hematocrit measurement into dialysis system without major alterations to the dialysis machine or transport tubing.

Abstract: A method for controlling supply of fuel to a combustion engine, e.g. a self-igniting internal combustion engine in a vehicle, having a first group of cylinders and a second group of cylinders, the method comprising the steps of: determining if a demanded total fuel quantity to the combustion engine is below a first predetermined total fuel quantity; and, if the demanded total fuel quantity to the combustion engine is below the first predetermined total fuel quantity, increasing the fuel supply to the first group of cylinders with a value determined by the demanded total fuel quantity and decreasing the fuel supply to the second group of cylinders with substantially the same value. Also, a second method, a computer program and an electronic control unit.

Abstract: A gear position in an automotive gearbox is detected on the basis of measuring a value indicative of the speed of a rotating shaft between an engine and the gearbox, and a value indicative of the speed of an output shaft from the gearbox, and calculating a quotient of these two speeds. If for a predetermined period of time the quotient is between upper and lower limits about a quotient value pertaining to the respective gear position, it is decided that a gear position obtains. Through information about a selected split position of a split gear it is as possible gear position rule out all gear positions which do not correspond to the selected split position, thereby enabling said upper and lower limits to be raised and lowered respectively for the remaining gear positions which correspond to the selected split position.

Abstract: In a multiple cylinder four-stroke engine with fuel injection, an interference oscillation is generated briefly on the flywheel on starting by varied fuel supply to different cylinders. After oscillation analysis of the resultant oscillation of the flywheel, phase positions of the superimposed interference oscillation and of the resultant oscillation are compared. If predetermined phase positions of the oscillations appear, the engine is considered to be operating in the correct cycle position, but otherwise a control unit is initiated to correct its cycle position so that the correct cycle position of the engine is obtained.

Abstract: In a multiple cylinder four-stroke engine with fuel injection, an interference oscillation (C) is generated briefly on the flywheel on starting by varied fuel supply to different cylinders. After oscillation analysis of the resultant oscillation (A′) of the flywheel, phase positions of the superimposed interference oscillation (D) and of the interference oscillation (C) are compared. If predetermined phase positions of the oscillations appear, the engine is considered to be operating in the correct cycle position, but otherwise a control unit is initiated to correct its cycle position so that the correct cycle position of the engine is obtained.

Abstract: An autofocusing system in which optimal or nearly optimal linear filters are selected for filtering an image signal so that the components of the image signal which contain image content, and thus, focus information are amplified while the components of the image signal which contain noise are damped. One set of nearly optimal linear filters are modified second order difference filters in which the number of internal zeros are modified to tune the filter to the particular equipment.

Abstract: An image registration (alignment) system which achieves alignment by determining an optimal focus for a composite image produced from the combination of misregistered images. The system also uses optimal or nearly optimal linear filters for filtering the combined image to emphasize (enhance) alignment information in the combined image and to de-emphasize (damp) noise. One set of the nearly optimal linear filters are modified second order difference filters in which the number of internal zeros are modified to tune the filter to the particular equipment.
